The circular sheet is then drawn into a bottomed cylinder. The cylinder is used as a case (1) with a gasket. A generating device (20) and a sealing plate (2) are placed in the case (1). The edge (2a) of the sealing plate (2) is caulked by the edge (1a) of the case (1) through the gasket (3) made of the resin and the case is sealed to produce a coin-shaped cell.</p> |
